Hanna star Saoirse Ronan has joined the cast of Ryan Gosling's fairytale noir film How To Catch a Monster. Matt Smith (Doctor Who), Christina Hendricks (Mad Men), and Eva Mendes have already been cast in the film.

This will be Gosling's first time directing a film, and the story "weaves elements of fantasy noir, and suspense into a modern day fairytale. Set against the surreal dreamscape of a vanishing city, Billy, a single mother of two, is swept into a macabre and dark fantasy underworld while her teenage son, Bones, discovers a secret road leading to an underwater town. Both Billy and Bones must dive deep into the mystery, if their family is to survive."

This sounds like it's going to be such a cool movie, and I hope Gosling is just as good at directing as he is at acting. There's no word on who Ronan will play in the movie, but she's a wonderful actress that I'm sure will be awesome in it. Her next film will be an adaption of the sci-fi alien love story, The Host.

Here's the full press release:
